| Outpatient visits (n) | 4 [3–6]—(1) | 4 [3–5]—(5) | 4 [1–5]—(13) |
| Hospital admissions (n) | 0 [0–1]—(1) | 0 [0–2]—(6) | 0 [0–1]—(13) |

Data are presented as median with interquartile range [IQR] or mean and standard deviation (± SD) followed by missing values (MV); ppFEV1, percent predicted forced expiratory volume in 1 s; numbers of consultations (hospital admissions) and hospitalizations recorded during the last 12 months before the visit.
